About this 0.78ct lab-grown oval diamond

This 0.78ct lab-grown oval sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG741523777 or 741523777. Listed at 20 retailers as of October 25, 2026, with prices from $419 to $1,654, a $1,236 spread on the same certified stone. Reve Diamonds lists it at $1,654. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
